My internet has gone out again and for what will be the 4th time I'll have scheduled a tech come out to look at the lines. The trend I've noticed is that the drop cable from the street to the house ...
Reading the DSLReports thread referenced below, it appears to be the same problem -- an open neutral on your electrical service. Since your electrical service neutral is open, the coax is serving as the neutral return path and is carrying a lot of current.
The only way coax gets that hot is if a lot of current is running through it -- which is not normal (under normal operation, the current is miniscule).
This is a life safety issue and requires immediate attention.
Call your power company immediately and report you have an open neutral, which is causing your cable coax line to carry current and catch fire. They should respond immediately.
Do not touch it. You don't want to become part of the return path for your power service.
Don't let a cable technician touch it -- same reason, it's an electrocution hazard.
He stated that this is a bad ground, he said he had the same issue with them.
My takeaway: it's either unintentional or intentional. I find it hard to believe your 4 techs and your neighbor's tech(s) missed a faulty grounding wire. Cox must be hiring techs at our Southern border.
On the other hand, Cox may be engineering faulty grounds into their install to maintain a healthy revenue from tech visits. How long have you had service with Cox?
My parents lived in this house prior to me, they had Cox telephone, cable TV, and internet with no issues. I've been here since September '20 and I have had service with Cox with the same issues ever since.
The difference between my parents and I is, I didn't rent my modem from Cox and only have internet service. I'm under the impression this is part of a wider home electrical issue for other reasons.
